Abstract
The utility model discloses a combined corrugated steel arch bridge, comprising an arch steel frame which is used for supporting a bridge surface, wherein the arch steel frame is formed by fastening and connecting an inner layer corrugated steel plate and an outer layer corrugated steel plate; a space formed by the inner and outer layer corrugated steel plates is filled with compression resistance filler. The combined corrugated steel arch bridge has the advantages that the corrugated steel plates are high in compressive strength, better in plasticity, resistant to corrosion, light in weight, convenient to construct, and low in cost; a large number of turnover materials are not needed, so that the combined corrugated steel arch bridge can be widely applied to engineering road construction, the industrialization degree of constructional engineering is improved, and the quality is further guaranteed; concrete which is filled internally is subjected to a press state from three directions, the strength of the concrete can be increased by about 50%, the stability of the corrugated steel plates is enhanced by the concrete which is filled internally, the wall thickness of the corrugated steel plates is reduced, and the construction cost is reduced; compared with the traditional construction material of the same level, the cross section is smaller, materials are saved, and the linetype is attractive.
Description
Technical field
The utility model relates to a kind of corrugated steel arch bridge, relates in particular to a kind of inside and outside two-layer combination type corrugated steel arch bridge.
Background technology
Tradition arch bridge engineering quantity is large, all higher to material and the consumption requirement of stone material and other constructional materialss, and construction simultaneously is comparatively complicated, and construction period is longer, and in addition, traditional supporting process is also higher to the demand of circulation material and construction machinery.The corrugated steel arch bridge is as the substitute products that make up this defective, it is that zinc-plated sheet material is increased its rigidity of section by bellows-shaped, and the new structure thing by assembling construction, the type of corrugated steel has galvanized anticorrosive type and the dual anticorrosion type corrugated steel of zinc-plated overlay film etc.Compare with the other materials prefabrication, corrugated steel have cross section little, lightweight, be convenient to deposit transportation, assembling fast, the advantage such as construction technology is simple, the construction period is short, it is used widely in highway construction.But be subject to the impact of corrugated steel sheet material and process technology limit, the corrugated steel arch bridge can only be applied to less of in the arch bridge of footpath.
The utility model content
The utility model purpose: the purpose of this utility model is to provide a kind of Combined corrugated steel plate arch bridge that is applicable to than the long-span bridge culvert.
Technical scheme: Combined corrugated steel plate arch bridge described in the utility model, comprise for the arch-shaped steel frame of supporting bridge floor, described arch-shaped steel frame is by internal layer corrugated steel and the symmetrical fastening of outer corrugated steel, at the space-filling resistance to compression filler of inside and outside two-layer corrugated steel formation.
Wherein, described arch bridge is spandrel-braced arch bridge, and its trussed construction fastens or is made of the individual layer corrugated steel by inside and outside two-layer corrugated steel is symmetrical.The bridge floor of described arch bridge fastens or is made of the individual layer corrugated steel by inside and outside two-layer corrugated steel is symmetrical.Described resistance to compression filler is expansive concrete, and concrete is full of in the space that the ectonexine corrugated steel forms and closely knit gapless.The ripple of described corrugated steel is vertical ripple.Described ripple is sine bellows or sectional corrugated, and wherein sine bellows is continuous, and sectional corrugated is discrete, such as Semicircular arched, low arch, box etc.Described inside and outside two-layer corrugated steel connects by galvanized bolt.Described arch-shaped steel frame is fixed on the bridge pier at its two ends by galvanized bolt.
Beneficial effect: the utility model compared with prior art, that its remarkable advantage is that corrugated steel has is cheap, lightweight, easy construction, certain plasticity, compressive strength is high, intensity is large, the characteristics such as corrosion-resistant, therefore can be widely used in the engineering road construction.Because steel plate itself has just had great second moment of area after forming bellows-shaped, after the ectonexine corrugated steel fastens, its radial constraint has limited inner concrete expanding, make inner concrete be in the three dimension stress state, thereby significantly improve the intensity of inner fill concrete, can improve its intensity 50% left and right.Inner fill concrete has strengthened the stability of corrugated steel, can reduce the corrugated steel wall thickness, has reduced cost,, economical with materials less than ad eundem traditional construction material cross section, does not need a large amount of circulation materials and linear attractive in appearance.Make up simultaneously the ripple steel plate structure and have longitudinal reinforcement and the laterally effect of cuff concurrently, and can be used as construction formwork, conveniently inner fill concrete builds.The joint number of corrugated steel, thickness, ripple parameter and bend radius all can be made different choice according to the actual requirements, so just can satisfy the different requirements across footpath and dissimilar bridge, and improve the range of application of this combining structure in managing environment variously.In work progress, the corrugated steel combining structure can be used as stiff skeleton, and its assembling process is simple, and is lightweight, thereby can simplify construction technology, shortens the construction period.
